How Does Skin React to Temperature Changes?

AI Thread Summary
The skin's response to temperature changes involves complex physiological and physical mechanisms. When temperatures rise, increased molecular energy leads to vasodilation, enhancing peripheral blood flow to cool the body through processes like sweating. Conversely, exposure to cold triggers vasoconstriction, reducing blood flow to conserve heat, which can result in shivering as the body attempts to generate warmth. These responses are crucial for maintaining homeostasis. Conditions like Raynaud's syndrome illustrate how abnormal responses to temperature changes can affect blood flow and skin health. Overall, the skin plays a vital role in thermoregulation through its metabolic reactions and blood flow adjustments in response to environmental temperature shifts.

How does our skin respond to changes in temperature?
 
Biology news on Phys.org
This question can be approached in many different ways, both from a physiologic and physical standpoint.

What happens when molecules get an increase in energy for one or another reason? How does the body respond to an increased temperature to keep the body cool? I'm sure you have undergone this process, which happens to occur in a hot, enclosed area or after some physical activity. What about when it gets cold? Have you ever stepped out of a warm shower and started to shake? How do cells respond to heat and cold? how is the metabolic reactions in the skin related to the surrounding temperature?
 
Largely by changing peripheral blood flow - restricting it during cold, increasing it during warmth.

google for Raynaud's syndrome, for example.

Thread 'I need help understanding this quote about recent Natural Selection'

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...

Thread 'Fermentation using mixed legume and grain feedstock'

I use ethanol for cleaning glassware and resin 3D prints. The glassware is sometimes used for food. If possible, I'd prefer to only keep one grade of ethanol on hand. I've made sugar mash, but that is hardly the least expensive feedstock for ethanol. I had given some thought to using wheat flour, and for this I would need a source for amylase enzyme (relevant data, but not the core question). I am now considering animal feed that I have access to for 20 cents per pound. This is a...
